Sunglasses are essential for eye protection against harmful UV rays, but choosing the right sunglass lenses is just as important. Whether you’re an outdoor enthusiast, a driver, or just looking for everyday sun protection, understanding the different lens types, coatings, and materials will help you make the best choice.
What Are the Best Lens Colors for Sunglasses?
Opticians and optometrists often recommend three main lens colors for prescription sunglasses and non-prescription sun lenses:
- Gray lenses: Maintain true color perception without distortion. Ideal for general use.
- Brown lenses: Increase contrast and enhance depth perception, making them popular for sports and outdoor activities.
- G-15 lenses: A mix of gray and green, providing balanced color perception with reduced glare, often preferred for prescription sun lenses.
If you need sunglasses that are not too dark, we advise gradient lenses, which are darker at the top and lighter at the bottom. These lenses are extremely useful for large frames, reducing the bulky appearance of the glasses. Moreover, they allow for easier reading because the lower part of the lens remains lighter.
Types of Specialized Sunglass Lenses
Mirrored Sunglasses
Mirrored lenses have a special coating that reflects more sunlight, reducing glare and adding an extra layer of UV protection. They are ideal for outdoor activities like skiing, hiking, and sailing. However, optometrists advise removing them when driving through tunnels to maintain visibility.
Polarized Sunglasses – Best for Glare Reduction
Polarized lenses are highly recommended by opticians for people exposed to excessive glare, especially near water, snow, or road surfaces. They significantly reduce eye strain and enhance visual clarity.
While polarized sunglasses are beneficial for outdoor activities and driving, some users report difficulty seeing digital screens or dashboard instruments in certain vehicles. Bus drivers and pilots have also noted reduced visibility through laminated glass. Always test polarized lenses before purchasing for driving or professional use.
Photochromic Lenses – Adaptive Sun Protection
Photochromic lenses (also known as transition lenses) adjust their tint depending on sunlight exposure. These are highly recommended for those who wear prescription glasses, as they eliminate the need to switch between regular eyeglasses and sunglasses. They provide 100% UV protection whether you are in the shade or under direct sunlight.
Lens Material: Glass vs. Organic (CR-39) Lenses
When choosing sunglass lenses, you must decide between glass lenses and organic lenses (CR-39). Both offer UV protection and excellent visual clarity, but they differ in durability and weight.
- Glass lenses: Provide superior scratch resistance but are heavier and prone to breaking if dropped.
- Organic lenses (CR-39): Lightweight and impact-resistant but more susceptible to scratches.
For everyday wear, opticians often recommend organic lenses due to their comfort and durability. Lightweight frames paired with organic lenses make sunglasses more comfortable for extended wear.
Final Recommendation from Optometrists & Opticians
Comfort is key when you’re choosing the right sunglasses. That’s why most opticians and optometrists recommend lightweight, UV-protected organic lenses for everyday use. If you have specific vision needs, consult a professional optometrist to find the best lens type for you.
